DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for displaying the operation status of a controller for controlling an industrial machine, a production line, a chemical plant, or the like, and for creating a display content.

[0002]

2. Description of the Related Art A controller called a programmable controller is widely used as a controller for controlling industrial machines, factory production lines, chemical plants and the like. The controller holds signals and data of the control target as input signals, output signals, auxiliary signals, counter values, timer values, and numerical data according to types. For example, on / off signals indicating opening and closing of switches, valves, and the like are input signals and output signals. The number of products to be produced is a counter value, the time value for taking the operation timing of the machine is a timer value, and the temperature and pressure are numerical data.

[0003] These signals and data are stored in a memory called a device in the controller (hereinafter collectively referred to as a device), and the controller performs an arithmetic operation on these devices according to the contents of a control program diagram. Control. Here, the control program diagram is a program that is also held in a memory in the controller in order to give a specification operation of a control target, and is created by a control designer using a control program diagram creating apparatus. A well-known relay ladder is widely used as a programming language.

FIG. 22 shows an example of a user operation screen of the control program diagram creator. A device symbol is assigned to a device to distinguish the type of signal or data. In FIG. 22, the input signal 120 is X, the output signal 121 is Y, the auxiliary signal 122 is M, and the counter value is 1.
23, C, timer value 124, T, numerical data 12
5 is given a D. Further, in order to distinguish a plurality of signals from a certain device symbol, a number called a device number is given after the device symbol.

Reference numeral 51 denotes an example of a means for inputting a sequence circuit symbol in a control program diagram. Buttons 511, 512, 513, and 514 having a title of a circuit symbol of a relay ladder are provided.
When you press the one you want to enter from among
The device selection means 126 for setting the device symbol and device number is displayed as shown in FIG. When the user presses the OK button 129, the setting 126 is received and closed by the device symbol selecting means 127 and the device number selecting means 128.

Next, the display will be described. In order to transmit the value of the device of the controller to an operator such as a production line, a display device called a display or a programmable display is widely used. The display has a display screen such as a CRT or a liquid crystal display, not only displays device data, but also has input means such as a touch panel. It also takes commands into the display and conveys them to the controller. The content displayed on the screen of the display unit varies depending on the specifications of the control target, and is created by the screen designer using the display unit drawing apparatus having the basic configuration shown in FIG. This work of designing the display contents is widely called drawing.

Next, the display device drawing apparatus will be described. The user operation screen of the display device drawing apparatus is as shown in FIG. 20, and has a drawing area 1 showing a display screen and a display part selecting means 2 for selecting a display part which is a component of display contents. The display components include a lamp component 21 having a lamp mode indicating particularly on / off of the device, a numerical component 22 for directly displaying the numerical value of the device, a meter component 23 for displaying the numerical value graphically and a meter or graph mode, and a graph component. 24, a character string component 25 for transmitting a message to an operator in accordance with device data, and a touch key component 26 for capturing an input signal from a touch panel into a display device.
Provides these with buttons.

[0008] Further, the selected display component indicates which device value is to be displayed, a detailed mode such as the shape and color of the component to be displayed, and additional functions performed during display.
It is necessary to set various attributes related to display. FIG. 21, which is opened by pressing each of the display component buttons constituting the display component selection means 2, is an operation screen for this purpose. The device selection means 110 for giving the attributes of the display component, the display mode selection means 113, the function selection during display Means 114 are provided. The device selecting means 110 further includes a device symbol selecting means 111 and a device number selecting means 112. FIG. 21 is opened when the button 26 of the touch key component in FIG. 20 is particularly pressed.

FIG. 24 shows a procedure for proceeding with drawing by a conventional display drawing device. In FIG. 24, the procedure is started from step ST30 of selecting a display component by the display component selection means 2 of FIG. 20, and thereafter, the step S of arranging the selected display component at a predetermined position in the drawing area is performed.
The process continues to T31, steps ST5 and ST6 for setting the display mode of the arranged display component and the function being displayed, and device selection step ST1 for selecting which device data is to be displayed on the arranged display component. The device selection step ST1 is a step ST11 of selecting the device symbol.
And ST12 for selecting a device number. Here, the steps after step ST30 of selecting a display component do not necessarily have to be in the order shown in FIG.
Exists at the beginning of the flowchart of FIG.

As described above, in the procedure of FIG. 24 in which the drawing is started from the display component selection step, the first work of the drawing is to determine what kind of component is to be displayed on the display screen. This is natural when the recognition of the image is recognized. This is effective when the design of the appearance of the screen is completed first, and then a drawing procedure is performed in which the value of the device to be displayed on each component is set.

[0011]

However, the above-described drawing procedure takes into consideration only drawing, and is a design procedure often taken when a control designer who creates a control program also serves as a screen designer. However, there is a problem that it is not suitable for simultaneous drawing while creating a control program. In such a case, a control and screen designer (hereinafter, simply referred to as a designer) thinks about what kind of control operation is to be performed on a certain device by a controller and how to display it on a display. To start.

When a conventional display drawing apparatus is used for a design procedure starting from a place where a certain device is focused, as shown in FIG. 25, once the device is focused, the device is designed once. Remember in the head of the person,
It is required to perform a temporary storage step ST40 of a device to be written down in another drawing or memo. After that Figure 2
The drawing work proceeds from the display component selection step as in the case of FIG. 4, but in FIG. 25, when the device selection step ST1 is reached, the device temporary storage step ST1 is started.
It is necessary to proceed to ST11 and ST12 for allocating a device symbol and a device number after a temporary storage call step ST41 for recalling the device stored in 40.

The temporary storage ST40 for such a device of interest takes time to write down in another drawing or the like, and the temporary storage is called back S.
For T41, it is time-consuming to look at the drawings for which the temporary storage has been written down, or forgotten even if the user memorizes it with his / her head, and the work efficiency is poor when considering the overall design of the control program design and drawing. It has become something.

In a process in which control program design and drawing are performed separately, in the conventional display drawing device, particularly when the display components, particularly the aspect, that is, the appearance specifications of the screen, are not determined, FIG. There was also a problem that the drawing work shown could not be started. This is because the display component selecting means 2 in FIG. 20 presupposes the mode of the display component. For example, when numerical data is displayed in the device in FIG. If it is not determined whether the display mode is the meter mode or the graph mode, the display component selection step ST30, which is the first step in FIG. 24, cannot be performed.

In fact, first, the control specifications of the controller are fixed,
Even when the control program is completed and the data of which device is to be displayed on the display device is determined, the form of each display component of the display device is often not determined.
In such a case, the drawing operation of the display is suspended from the initial stage.

Further, the device to be displayed needs to be input to the control program diagram creating apparatus in order to perform the control operation.
Device setting means such as the device selecting means 126 shown in FIG. Since this means is separate from the device setting means 110 of the display device drawing apparatus of FIG. 21, the designer must input both in the display device drawing device and the control program generation device to set the same device. In addition, there is a problem that two types of operation of both devices must be learned. In some cases, a comment that explains the role of the device is added to the device. This comment setting must be performed by the control program diagram creation device and the display device creation device, and has the same problem.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-described problems. When the control program design and drawing are performed simultaneously, the step of temporarily storing a device of interest is omitted. An object of the present invention is to provide a display drawing device that improves efficiency.

Here, ST20 can be placed at any position in FIG. 9 as long as it is within loop LP1. Since the setting contents required for the operation in the loop LP1 are only those relating to the device, even when the specifications other than the device such as the display mode and the function being displayed among the specifications required for the display device are not determined, Only the drawing work in the loop LP1 can be performed ahead of schedule.

If the display mode and the function during display are determined for some of the devices, the determined settings can be obtained by combining the loop LP1 and loop LP2 repetition procedures. Can be done ahead of schedule.

When the drawing operation is interrupted halfway,
The data of the display content includes information on only the selection of the device and the setting of the type of the display component, the display mode, and the function being displayed are suspended. FIG. 10 shows the data structure of the constituent elements constituting the display contents. Among them, FIG. 10 shows the type of the display component, the display mode, and the state in which the function being displayed is suspended. In FIG. 10, hexadecimal FFFF is set in the memories 40, 41, and 42 for storing the suspended setting values as an example of the value indicating the suspension. As another method of giving the hold status, there is a method in which the device itself gives a provisional initial value (default value) without a user explicitly setting a value. It can also be used for the embodiments.

As described above, in the fourth embodiment, after performing the device selection step, the drawing operation is interrupted before the selection of the display component and the selection of the display mode and the function being displayed are completed, and only the device selection is performed. Can save the drawing data that contains the information of the display device, so that even when the specifications of the display components of the display unit are not determined, it is possible to start the drawing work with the step of allocating devices ahead of schedule, and to improve the drawing efficiency Can be.
